AbstractPackaging based on immobilization of antimicrobial enzymes provides a promising form of active packaging systems applicable in food processing. Glucose oxidase and lysozyme were immobilized by the Ugi reaction with cyclohexyl isocyanide and glutaraldehyde on polyamide and ionomer films partially hydrolysed by hydrochloric acid. The immobilization of the enzymes on the surface of films was confirmed by FT-IR spectroscopy and the films were characterized by the specific activity of the immobilized enzymes. The enzyme migration into model solutions and the effect of pH, temperature and storage time on the activity of immobilized enzyme were also evaluated. Immobilization of lysozyme onto polyamide and ionomer films resulted in the loss of enzyme activity. The polyamide and ionomer films with immobilized glucose oxidase inhibited the growth of bacteria Escherichia coli CNCTC 6859, Pseudomonas fluorescens CNCTC 5793, Lactobacillus helveticus CH-1, Listeria ivanovii CCM 5884 and Listeria innocua CCM 4030 on agar media.

Abstract We describe a novel fluorometric technique for simple, rapid, and economical assay of glucose by use of immobilized glucose oxidase and peroxidase. A cylindrical magnetic stirrer was specially designed to hold the immobilized enzymes firmly and to allow the reaction minzymic transformation quickly. Blood plasma can be assayed directly with no pretreatment. Ascrobic acid, uric acid, and creatinine in concenctrations of 0.25, 0.25, and 0.2 g/liter, respectively, did not interfere. The linearity of the assay was extended to 4.0 g of glucose concentrations. Results by our technique and by the otoluidine or hexokinase methods agreed well. The immobilized enzymes are stable for several months and can be used for several hundred highly accurate and reproducible assays.
